The GEOSGeometry equality operator now also compares SRID. The OpenLayers-based form widgets now use OpenLayers 3, and the gis/openlayers.html and gis/openlayers-osm.html templates have been updated. Check your project if you subclass these widgets or extend the templates.

Fixed a regression in 1.11.3 on Python 2 where non-ASCII format values for date/time widgets results in an empty value in the widget’s HTML (#28355). Fixed QuerySet.union() and difference() when combining with a queryset raising EmptyResultSet (#28378).

This is wrong for URLs whose unquoted form contains a %xx sequence, but such URLs are very unlikely to happen in the wild, because they would confuse browsers too.

In Django 1.3, the get_initial method of the django.views.generic.edit.FormMixin class was returning the class initial dictionary.

The CSRF-protection system is based on a random nonce sent to the client in a cookie which must be sent by the client on future requests and, in forms, a hidden value which must be submitted back with the form.

Release notes Django 1.5 release notes Backwards incompatible changes in 1.5Changes in tests execution

This should not cause any problems unless you have existing doctests which assume a TransactionTestCase executed earlier left some database state behind or unit tests that rely on some form of state being preserved after the execution of other tests.

Release notes Django 1.5.6 release notes

The CSRF-protection system is based on a random nonce sent to the client in a cookie which must be sent by the client on future requests and, in forms, a hidden value which must be submitted back with the form.

Release notes Django 1.6 release notes Features deprecated in 1.6

Previously, if you wanted a ModelForm to use all fields on the model, you could simply omit the Meta.fields attribute, and all fields would be used.

Release notes Django 1.6 release notes Features deprecated in 1.6

The generic views CreateView and UpdateView, and anything else derived from ModelFormMixin, are vulnerable to the security problem described in the section above, because they can automatically create a ModelForm that uses all fields for a model.

Release notes Django 1.6.3 release notes

The CSRF-protection system is based on a random nonce sent to the client in a cookie which must be sent by the client on future requests and, in forms, a hidden value which must be submitted back with the form.

Release notes Django 1.7 release notes Features deprecated in 1.7

If you relied on these methods to alter structures like form fields, you should now treat these OrderedDicts as immutable objects and override them to change their content.

Release notes Django 1.8 release notes Backwards incompatible changes in 1.8

InlineModelAdmin now has an attribute show_change_link that supports showing a link to an inline object’s change form. Use the new django.contrib.admin.RelatedOnlyFieldListFilter in ModelAdmin.list_filter to limit the list_filter choices to foreign objects which are attached to those from the ModelAdmin.

Release notes Django 1.8 release notes What’s new in Django 1.8Minor features

The new SingleObjectMixin.query_pk_and_slug attribute allows changing the behavior of get_object() so that it’ll perform its lookup using both the primary key and the slug. The get_form() method doesn’t require a form_class to be provided anymore.

Release notes Django 1.8 release notes Features deprecated in 1.8

The original_content_type_id attribute on InlineAdminForm has been deprecated and will be removed in Django 1.10. Historically, it was used to construct the “view on site” URL. This URL is now accessible using the absolute_url attribute of the form.

Release notes Django 1.8.8 release notes

Corrected __len query lookup on ArrayField for empty arrays (#25772). Restored the ability to use custom formats from formats.py with django.utils.formats.get_format() and the date template filter (#25812). Fixed a state bug when migrating a SeparateDatabaseAndState operation backwards (#25896).

Release notes

This release starts Django’s use of a loose form of semantic versioning, but there aren’t any major backwards incompatible changes that might be expected of a 2.0 release. Upgrading should be a similar amount of effort as past feature releases.

If you want to preserve the 30 character limit for last names, use a custom form: If you wish to keep this restriction in the admin when editing users, set UserAdmin.form to use this form:

Release notes Django 2.1 release notes What’s new in Django 2.1Minor features

The new ModelAdmin.get_deleted_objects() method allows customizing the deletion process of the delete view and the “delete selected” action. The actions.html, change_list_results.html, date_hierarchy.html, pagination.html, prepopulated_fields_js.html, search_form.html, and submit_line.html templates can now be overridden per app or per model (besides overridden globally).

Release notes Django 2.1 release notes Features deprecated in 2.1

Support for SQLite < 3.7.15 is removed. The date format of Set-Cookie’s Expires directive is changed to follow RFC 7231 Section 7.1.1.1 instead of Netscape’s cookie standard. Hyphens present in dates like Tue, 25-Dec-2018 22:26:13 GMT are removed.

Release notes Django 2.1.1 release notes

Fixed translation failure of DurationField’s “overflow” error message (#29623). Fixed a regression where the admin change form crashed if the user doesn’t have the ‘add’ permission to a model that uses TabularInline (#29637).
